Altogether, 75 alien beetle species have been revealed, which represents 2.98% of local coleopteran fauna. The most numerous taxonomic groups are Curculionidae (30 species), Staphylinidae and Chrysomelidae (by 11).

Republic of Moldova at the crossing point Their activity can alter ecosystems of three biogeographical zones (Central structure and functioning and eventually European, Eurasian and Mediterranean) lead to the extinction of native species, along with the intense human activities inducing biodiversity losses [Elton, 1958; makes it especially prone to alien species Nentwig, 2008; Hulme et al., 2009].
